The letters marked as red has code conversion (all three letters) and display (2 letter Єє,Її. See above the red field!) conflict. Because, these letters are before (on windows 1251) not official implemented in standard fonts. Since UNICODE standard 3.0 (ISBN 0-201-61633-5) there are implemented in the range 0400-04FF. I have written above all codes in decimal system. (in hexdecimal, the CRYLLIC CAPITAL LETTER STRAIGHT U = 04AE, the CRYLLIC SMALL LETTER STRAIGHT U = 04AF, the CRYLLIC CAPITAL LETTER BARRED O =04E8, the CRYLLIC SMALL LETTER BARRED O =04E9)
You can become a problem to display these two letters in non-unicode fons. I have found in the "Arial Unicode MS", "Microsoft Sans Seruf" and in some new fonts. !!! In "Lucida Sans Unicode" placed STRAIGHT U right, but BARRED O is placed in another order. (Year, 2000)
This table is used by most common people. But it's not standard! Thus, I can say, it's traditional table.

The letters marked as green are changed. I think, it's more intelligent because repeatability will be reduced by this table. My convert programm uses this second table. I will improve the programm as soon as possible. :)) If you have any question or feedback, don't hesitate to contact me.
